Gila Monster is one of the 130 Planet Zoo 2 launch species. It is housed in a Exhibit habitat, accepts the Desert biome, carries a no barrier requirement and is listed at 0.56 m (length). It shares a biome and an enclosure type with 5 other species, but the official species data rules out every one of those pairings, so it needs a habitat of its own.
Every figure on this page comes from the official Planet Zoo 2 Zoopedia export rather than trailer footage: biome, enclosure type, barrier grade, size and the compatibility verdicts are all taken from the game's own data.

Gila Monster needs a Exhibit enclosure and accepts the Desert biome. The barrier requirement is none at all, and that is the number to check before building: a Grade 4 animal behind a Grade 1 wall is the most common way a first zoo stalls.
Gila Monster shares a biome and an enclosure type with 5 other species, but every one of those pairings is ruled out by the official data, because one side of each pair is officially solitary.
